To all vfw/wm it may concern:

Be it known that I, Louis N. STnvnNoT, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Trailer' Attach-l ments, of which the following is a specltication.

rIhe present invention relates to means for connecting a trailer to a self-propelled veh1 cle which will insure the trailer traveling in substantially the same path as the veh 1- cle, when the latter is turning a corner or rounding a curve. The obJect of'the invention is to provide such-means which .will be cheap and simple in construction, which will not require any material change in the mechanism of the vehicle, and which can be readily adjusted to fit vehicles of all sizes.v

In the accompanying drawing, Figure l is a plan view of a self-propelled vehicle anda trailer connected in accordance with my invention, certain parts being broken away or omitted; Fig. 2 is an enlarged plan view. illustrating the connection between the vehicles; Fig. 3 is an enlarged vertical section' of a portion of the trailer; Fig. 4 is a cross sec- `self-propelled vehicle. 'Io the rear bar zftof tional view on the line 4--4 of Figfti', Fig. 5 is a vertical cross section on the li-ne 5.-5 4 of Fig. 2; Fig. 6 is a similar cross section on the line 6 6 of Fig. l..

Referring to the drawing, l indicates 'a the frame 3 of said vehicle is attached a bar 4, which extends rearwardly, and to a re duced rear end 6 of said bar is pivoted, as shownat 7, a forkedy forward end of a lon`- gitudinally extending pole 8, to which is Secured, as shown at 9, a ring ll.

Upon said lower ring V11 is plvotally mounted an upper ring 12, which is secured to transverse bars 13 of the body 14 of 'ag trailer. Longitudinal members I6 of `said bodyl have rslidable engagements 17 with the'.V

ends of carriage sprn'ngs 18, supported at their middle points uponla wheel' axle 19,'

f 'carrying at, its ends wheelsl 2l. A front.

4 member 22 of the frame of said body 'is also supported on upper and lowerrollers 23, 2t, the ends of which are carriedby brackets 29 y ,nel-shaped pole 8 and additionally supportchange in direction of body,

of the pole as said arm.

on` the upper and lower sides of said pole 8,A here `shown as a channel iron.

To the arms 27 which turn the steering knuckles 28 are secured, as shown at 29, extensions 31, and, to the ends of said extensions 31 are pivotally secured, as shown at 32, the front ends of rods 33, extending rearwardly through guide-ways or supports secured to the frame 3 and screwed into sleevr 3i which are cach pivotally connected at their rear ends, as' shown at 36, to any one of a series of holes 3T in an arm 38, the inner end of which is pivotally secu'red, as shown at 39, to a cross bar t0, secured to the chan- ,65 ed by oblique struts 4:2 connected to said pole. Said arm is slidably supported by a guide-way secured as shown at 35 to the cross bar 40. In any one of the holes 37 in said arm 38 is pivoted the front end of a rod 43, the vrear end of which is pivotally connected, as shown at it, to anl arm t6 eX- tending from a clamp` 47 which clamps the carriage spring'to the axle shaft.

It results from this construction that any the front wheels 48 is accompanied by a change in the opposite direction of the wheels 2l of the trailer, thus facilitating the turning of the trailer with the turning of the vehicle.

l. In combination with an automobile, in-

y ward'extensions secured to the steering arms extending from the steering knuckles of the front 'wheels of the automobile, a trailer a pole therefor pivotallyconnected to a rear portion of the 'frame of the automobile to vibrate vertically, an axle on which said body is supported to turn horizontally relative thereto,- a cross bar on the' front portion of said pole, arms ,ivoted to said cross bar on opposite sides of) the pole, and links connecting each arm with the extension and the wheel anleof the trailer 'on the same side v 95 2. In combination'with an automobile, inward extensions secured to the steering armsextending from the steering knuckles of the frontV wheels of the automobile, a trailer body, a pole therefor pivotally connectedfto 10A a rear portion of the automobile to vibrate vertically. an axle upon which said body is supported to turn horizontally relative thereto. a cross bar on the front portion of said pole, arins 4pivoted to said cross bar on opposite sides ofthe pole, links extending forwardly and rearwardly and connecting each arm with the extension and the Wheel axle of the trailer on the same side of the i pole as said arm, a loop-shaped guide for said arm extending longitudinall)Y of the vehicle and secnred to the vross bar, and a loop-shaped guide for the forward link extending transversely of the vehicle and Secured to its frame.
